Questions about the U-values poster

What’s on the U-values poster?

The rule, 3 worked examples, and the mistake everyone makes. The U-value is heat lost per square metre per degree of temperature difference, in wa…; U = 1 / total R · units W/m2K; R total 5.0 = U = 0.20; Solid brick wall = U about 2.1; Triple glazing = U about 0.8; Common mistake: Comparing 0.30 and 0.20 as small → That is a third less heat lost. Educational reference. Required values are set by national building regulations and change; check the current document.

Who is the U-values poster for?

U-values belongs to the Architecture section rather than to a school year, because design is not something one grade owns. Anyone learning environmental design can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the U-values poster?

Use it when comparing build-ups. Lower is better, and it is not a linear scale of comfort. A wall chart earns its place by being glanceable from where the work is happening, so U-values belongs on the wall where that design work actually happens, within glancing distance, rather than filed away.

What other posters go with U-values?

Airtightness, Embodied Carbon and Orientation sit alongside U-values in the Architecture section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AirtightnessEmbodied CarbonOrientation

Is the U-values poster free to download and print?

Yes. U-values downloads as a free PDF with no account, no email and no watermark, like everything else in the Architecture section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence

What size does the U-values poster print at?

U-values is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of U-values loses nothing.Printing guide
